2. Lubricants
2.1 General information
Lubricants are selected specifically for the relevant application.
The manufacturer or operator of the machine should ideally
make the selection in consultation with the supplier of the
lubricant. If you have no or little experience in selecting
lubricants for lubrication systems, please contact us. We would
be happy to assist you in selecting suitable lubricants and
components to build a lubrication system optimized for your
particular application. Consider the following points when
selecting/using lubricants. This will spare you potential
downtime and damage to the machine or lubrication system.
2.2 Material compatibility
The lubricants must generally be compatible with the following
materials:
•Plastics: ABS, CR, FPM, NBR, NR, PA, PET, PMMA, POM, PP,
PS, PTFE, PU, PUR
•Metals: steel, gray cast iron, brass, copper, aluminum
2.3 Temperature properties
The lubricant used must be suitable for the specific ambient
temperature of the product. The viscosity approved for proper
functioning must neither be exceeded at low temperatures nor
fall too low at high temperatures. For the approved viscosity,
see the “Technical data” chapter.
2.4 Aging of lubricants
Based on past experience with the lubricant used, checks should
be conducted at regular intervals defined by the operator, to
determine whether the lubricant needs to be replaced due to
aging processes (oil separation). In case of doubt regarding the
continued suitability of the lubricant, it must be replaced before
the system is started up again. If you do not yet have any
experience with the lubricant used, we recommend conducting
a check after just one week.
2.5 Avoidance of faults and hazards
To avoid faults and hazards, please observe the following:
•When handling lubricants, observe the relevant safety data
sheet (SDS) and any hazard labeling on the packaging.
•Due to the large number of additives, some lubricants that
meet the pumpability requirements specified in the manual
are not suitable for use in centralized lubrication systems.
•Whenever possible, always use SKF lubrication greases. They
are ideal for use in lubrication systems.
•Do not mix lubricants. This can have unpredictable effects on
the properties and usability of the lubricant.
•Use lubricants containing solid lubricants only after technical
consultation with SKF.
• The lubricant’s ignition temperature has to be at least
50 kelvin above the maximum surface temperature of the
components.
2.6 Solid lubricants
Solid lubricants may only be used after prior consultation with
SKF. When solid lubricants are used in lubrication systems, the
following rules generally apply:
Graphite:
•Maximum graphite content 8%
•Maximum grain size 25 µm (preferably in lamellar form)
MoS2:
•Maximum MoS2 content 5%
•Maximum grain size 15 µm
Copper:
•Lubricants containing copper are known to lead to coatings
forming on pistons, bore holes, and mating surfaces. This can
result in blockages in the centralized lubrication system.
Calcium carbonate:
•Lubricants containing calcium carbonate are known to lead to
very heavy wear on pistons, bore holes, and mating surfaces.
Calcium hydroxide:
•Lubricants containing calcium hydroxide are known to harden
considerably over time, which can lead to failure of the
centralized lubrication system.
PTFE, zinc, and aluminum:
•For these solid lubricants, it is not yet possible to define any
limit values for use in lubrication systems on the basis of
existing knowledge and practical experience.

Reservoir
The reservoir stores the lubricant. Different reservoir designs
and reservoir sizes exist in accordance with the pump variant.
Reservoir cover
Is used to fill the reservoir with clean and suitable lubricant, and
also to protect the lubricant from contamination.
Reservoir ventilation
Aerates the reservoir while the pump is working and lubricant is
being fed.
Stirring paddle
The stirring paddle homogenizes and smooths the lubricant
while the pump is running. In addition, the lower vertical part of
the stirring paddle presses the lubricant in the direction of the
pump elements and improves the suction characteristics of the
pump as a result.
Pump housing
The pump housing contains the motor, the electrical
connections, the filler nipple, the pump elements, the power
supply board and (if applicable) the intermittent low-level signal.
Pump elements
The pump can be equipped with up to 3 pump elements.
Filler nipple
Used for filling the pump from below. Once the filler nipple is
removed, corresponding accessories can be used to connect the
external grease return from the pressure limiting valves to the
pump elements through this port.

The transparent screw cap allows viewing of the LED indicators
(of operational and fault states) on the control circuit board. The
control elements (rotary switch for setting the time, button for
fault acknowledgment and additional lubrication) can be
accessed by removing the screw cap.
Control circuit board
The control circuit board is located behind the threaded closure
mechanism.

Control circuit board H is used to control P203 lubrication
pumps on vehicle trailers without permanent voltage supply.
Activation of control circuit board H is effected by the first
braking of the vehicle after it has been switched on.
There is a capacitor on the circuit board that safeguards the
power supply to the control circuit board.

The capacitor on control circuit board H is charged every time
the vehicle brake is actuated by the supply voltage of the brake
light. The necessary supply voltage of the control circuit board
for saving the interval and lubrication time and for the function
of the shock sensor is secured for 4 to 5 days (discharge time of
the capacitor).
If the vehicle is traveling, then this will be detected by the shock
sensor and the unchangeable availability time (A) and the
variable pause time (B) will expire.
The pause time (B) for the duration of the standstill will be
stopped for each vehicle standstill period. Standstill times are
not added to the availability time (A).
A lubrication is carried out for the duration of each brake
application until the lubrication time set on the control circuit
board (C) has been reached. No further lubrications are carried
out afterwards during brake applications.
After 6 hours, the pump ends the availability time (A) and starts
a new cycle.
NOTE
During downtimes which are longer than the discharge time
of the capacitor, the saved pause time that has already
expired is lost.
The pause time starts again from the beginning when the
brake is actuated once again. This is to be taken into
account with vehicle
trailers which are moved only briefly
and then remain at a standstill for prolonged periods
afterwards.
Additional lubrications may be necessary in
such cases.

Filling options
Depends on the pump design:

Reservoir cover (with reservoirs without a follower plate)
•Optional fill connection
1) The specified ambient temperature range requires that the lubricant used can be pumped at the given ambient temperature. The upper
limit of the ambient temperature is load-dependent and is determined primarily by the running time and the operating pressure. The
cyclic duration factor specified is applicable for NLGI 2 lubricants, an ambient temperature of 60 °C [140 °F], and a mean back pressure
on the pump element of 160 bar [2321 psi]. The maximum ON time should be reduced in the case of temperatures ≥ 60 °C [140 °F]
and heavy loading (meaning higher pressure). UL-certified pumps can only be operated up to a maximum permissible ambient
temperature of 60 °C [140 °F] regardless of the loading.
2) If an inclined position is expected (e.g. on construction or agricultural equipment), the following applies:
–The maximum filling must be reduced in accordance with the inclination to be expected (< MAX mark).
–The minimum fill level must be increased if the expected inclination is > 30° or more, otherwise functioning could be impaired due to
a reduced amount of lubricant in the suction area of the pump.
3) Observe the restrictions in the section "Operational limits of the intermittent empty signal".

1) The specified enclosure rating of the pump requires the use of IP6K9K-capable connection sockets and corresponding cables.
Classification is in accordance with the lowest enclosure rating when connection sockets and cables with low type of protection are used.
The achievable types of protection when using the connection sockets and cable which we supply can be found in the “Spare parts”
chapter.
4.3 Nominal delivery rates
NOTE
The specified nominal delivery rates per stroke apply to NLGI grade 2 lubrication greases in the case of pump elements 5, 6, 7, and R
and to NLGI grade
0 lubrication greases in the case of pump element L, in all cases at an ambient temperature of +20 °C [68 °F] and
a back pressure of 100
bar [1450 psi] at the pump element.
Differences in operating conditions or a different pump configuration will lead to changes in the motor speed and thus to a c
hange in
the delivery rate per unit of time. If the change in the
motor speed necessitates an adjustment to the delivery rate per unit of time,
then this will be reasonably accomplished by adjusting the lubrication and pause time setting of the pump.

1) With pump element L, lubricants below NLGI grade 2 can be pumped without restriction as specified in these instructions. For lubricants
of NLGI grade 2, the suitability of the pump element L for temperatures of -5 °C or lower must be checked on a case-by-case basis.
